WILLIAM N. LONG, OF EUGENE, OREGON.

FLOAT-VALVE FOR FLUS-l'G-TANKS.

Application filed February 20, 1908.

To all whom it may concern.'

Be it known that I, WILLIAM N. LONG, a l

citizen of the United States, and a resident of Eugene, in the county ofLane and State of Oregon, have invented a new and useful improvement inF lOat-V alves for Flushing- Tanks, of which the following is a full,clear,

and exact description.

The purpose of the invention is to provide a loat valve for water-closetilushing tanks, that will be effective in operation. and very simple inconstruction.

lt is a further purpose of the invention to provide a very quick actingvalve, and one that when opened will direct the water to the bottom ofthe tank, and which when closed will be perfectly concealed, theoperation of opening and closing the valve being automatic.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the `ligures.

Figure 1 is a section through a tank and a side elevation of theimproved valve installed therein 5 Fig. 2 is a vertical section throughthe valve and a side elevation of an accompanying' supply pipe,illustrating the valve closed. vation of the valve in open position, andFig. a is a vertical section showing a niodified construction in whichthe gasket is partially inclosed.

A represents a flushing tank ol the customary construction. A pipe 1()is introduced into the bottom of the tank A, being screwed therein or'fitted to place in any suitable or approved manner, and this pipe 10 isprovided with one or more washers 11 that bear against the bottom of thetank, being held in position by a nut 12, and a union 13 is illustratedin Fig. 1, that connects the 'fitting or shorter pipe 10 to a pipe 1.5athat supplies water to said pipe 10. A valve is iitted into the upperportion of the shorter pipe 10, and the lower portion 10a of this valveis shown introduced into the said pipe 1G and is secured thereto in awater-tight manner, and the body or lower portion 10'd of the valve isprovided with a lange le, that is located Specification o LettersPatent.

I above the upper face oi' the bottom of the flushing tank A, and restsupon a suitable washer 15, as is shown in Figs. 2 and 3: rlhe upperportion 16 of the valve, or that portion that extends beyond the flange14, is rcduced in diameter and may be of any suitable length, and isprovided with an opening 17 through which the water escapes into thesaid flushing tank. This opening i7 may be made in any suitable orapproved manner, and just below the opening 17 in the upper portion olithe valve, a washer or gasket 18 is made to surround the said upperportion 1G, and to bear upon the flange 14, and. this washer or gasket18 is ot conical formation and is adapted to act as a seat for theclosing member ol the valve to be hereinafter referred to. A conicalmember L9, constructed of rubber or leather, is secured to the upperportion of the valve by means ot' a screw 20 or its equivalent@ and thisconical member 19 is made to 'Hare outwardly and downwardly to a greateror less extent, and terminates at its lower end at the upper portion ofthe opening 17 in the upper section oiu the said valve, as isillustrated in Figs. 2 and 3. A regulating or controlling cap 21 is usedin connection with the upper portion of the valve. This regulating orcontrolling cap 21 is of metal and is closed at its top and is open atits lower end, and in the closed position of the valve shown in Fig. 2,the said cap 21 at its lower edge rests snugly and tightly upon therubber gasket 18 surrounding the upper portion 1G of the valve. A lever22 is attached to the upper portion olE the cap 21 in any suitable orapproved manner, and this lever 22 is provided with a socket 23, inwhich socket the stem 24 ot the float valve 25 is `fitted in anysuitable or approved manner. This lever 22 is fulcrumed upon an arm 26that extends up from the -flange 14, forming a portion of the body ofthe valve, as is clearly shown in Figs. 2 and 3. The regulating orcontrolling cap 21 is provided with an opening 27 that permits theoutward passage of air or any water that may be contained therein, andtherefore enables the said cap 21 to operate with accuracy and withdespatch. In the forni shown in Fig. 4- the parts 15, 1S, 19, 20, 21,22, 26 have the same construction as described in relation to the other'figures. The gasket 18, however, is seated in a depression 14a in thelange 14h. The tube 16a corresponding to the upper portion 16 of thevalve, as shown in the other iigures, is threaded at its lower end andscrewed into the 'liange lil", which is threaded lor the purose ofreceiving it. By this arrangement the tube a is rendered detachable.

ln the operation of this valve, when thc water is drawn oli .in thecustomary way from the tlushing` tank A, the volume that passes out isgreatly in excess oi the water that enters the tank tl'irough the valve10a. Consequently, as the level of the water in th, tank A is lowered,the 'float 25 descends and the cap 2l is proportionately raised,permitting the water Vfrom the inlet pipe 13a to gain access to the saidtank A, and as the water enters the tank it is directed downward towardits bottom by the conical member 19,

and the entrance of the water to the tank is thus renderedmore or lessnoiseless. llllien sullicient water has been received in the tank tocarry the iloat to its upper position, the regulating or controlling`cap 2i is carried down to its seat on the rubber gasket 18 and 1 thesupply of water to the tank is consequently cut oil,

Having thus described my invention7 lclaim as new and desire to secureby Letters Patent,-

1. Aln a valve lor llushing tanks, a valve l having an enlarged inletand small outlet, the outlet being located near the upper portion olithe valve, which Aupper portion is closed, a conical outwardly flaringmember secured to the upper portion of the valve extending down to theoutlet tliereolt, a

which cap is adapted to be seated upon the aforesaid conical gasket.

2. ln a valve 'for 'flushing tanks, the coml bination with a bodyportion larger at its lower end than at its unoer end said bodv Y i L l7 portion oi the valve being closed at its upper end and provided withan outlet opening adjacent to said upper end, a member constructed oil'leirible material and secured to the upper end portion oi.' the valve,and ex tending down to a point adjacent to the upper portion olf theoutlet et the valve, an elastic gasket et conical formation locatedaround the body portion of the valve at a point adjacent to and belowthe lower edge ot the outlet o'l the valve, a bracket, a lever carriedthereby, a float connected with the said lever, and a cap pivotallyconnected with the said lever and having a movement around the outletportion ot the valve to yand l from the aforesaid conical gasket.

3. ln a valve, the combination of a member provided with an opening lordischarging a liq uid, a valve seat encircling said member, controllingcap movable relatively to said seat and adapted to engage the same lorthe purpose ol stopping the flow of liquid through said opening,Heat-controlled mechanism connected with said controlling cap 'for thepurpose ol moving the same relatively to said seat, and mechanismconnected with said controlling cap and with said inst-mentioned memberfor the purpose of rendering noiseless the flow ol said liquid throughsaid opening. i el.
